I would like to control four AC indoor units from pluto. Of cource control them over IR with the gc100 should work with most of them. But I would prefer connecting them directly by wire. Toshiba, Daikin and Mitsubishi have LON-gateways, but they are very expensive.
Does somebody know AC indoor units which can be easily connected to PC technology (perhaps over RS232 or something) ?
Any experience in that? Or is the IR option still the better one?
